second point
the content references (aka Iceberg snapshots) are no longer used. This information can be used to no longer expose the affected e.g. Iceberg snapshots in any table metadata.

The docs say "Future Enhancements" - it's not there.

Has anyone found a workflow to handle deleting orphaned completely unreferenced files from object store?
